Risk factors for malnutrition in older Parkinson's disease patients: a Vietnamese cross-sectional study.
Article in BMC nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMalnutrition is a common but often underdiagnosed condition among individuals with Parkinson’s disease (PD), particularly in low- and middle-income countries. This study aimed to assess the prevalence of malnutrition and identify its associated clinical, functional, and metabolic factors in hospitalized older adults with PD in Vietnam.
methodsA cross-sectional study was conducted on 212 individuals diagnosed with PD. Nutritional status was evaluated using the full version of the Mini Nutritional Assessment (MNA). Multinomial logistic regression was performed to explore predictors of malnutrition and risk of malnutrition, using normal nutritional status as the reference group.
resultsOverall, 55.7% of participants were either malnourished (12.3%) or at risk of malnutrition (43.4%). Inpatient status (RRR = 0.19, p = 0.010; RRR = 0.51, p = 0.08), metabolic disorders (RRR = 0.14, p = 0.023; RRR = 1.15; p = 0.82) and instrumental activities of daily living (IADL) dependence (RRR = 0.06, p = 0.017; RRR = 0.52, p = 0.11) were associated with malnutrition, while female sex (RRR = 3.38, p < 0.001; RRR = 5.23, p = 0.014), depression (RRR = 6.38, p < 0.001; RRR = 6.63, p = 0.008), and motor complications (RRR = 1.17, p = 0.043; RRR = 1.32, p = 0.021) predicted both at-risk and malnutrition status.
conclusionMalnutrition and nutritional risk are highly prevalent among Vietnamese individuals with PD and are closely linked to motor, psychological, and functional impairments. This study provides the first evidence from Vietnam identifying key predictors of malnutrition in this population. Routine nutritional screening using tools like the MNA, integrated into multidisciplinary care, is critical for early detection and intervention in older PD patients, particularly in LMIC settings.
